Behavioral state and the premature’s readiness performance to begin oral feeding

Factors Affecting Oral Feeding Ability in Indonesian Preterm Infants

Most preterm infants exhibit atypical and immature feeding skills. Even though preterm infants have fulfilled the oral feeding readiness criteria, they still do not have optimal oral feeding ability. This study aimed to determine various factors affecting oral feeding ability in Indonesian preterm infants who have fulfilled oral feeding readiness criteria but still have not been able to feed orally. A cross-sectional study included 120 preterm infants admitted to five tertiary hospitals in Jakarta, Indonesia. Participants were preterm infants born at 28-34 weeks gestational age who had fulfilled the oral feeding readiness as the inclusion criteria: (1) stable cardiorespiratory status, (2) have achieved full enteral feeding via orogastric tube (OGT) 120 mL/kg/day without vomiting or bloating, and (3) strong and rhythmic non-nutritive sucking (NNS) through objective measurement. Infants' oral feeding ability and various factors that were assumed to affect oral feeding ability, including physiological flexion postural tone, physiological stability, rooting reflex, self-regulation, behavioral state, and level of morbidity were evaluated. Chi-square and multivariate analysis with Poisson regression were performed. Results indicated that postural tone, rooting reflex, physiological stability, self-regulation, behavioral state, and level of morbidity were significantly related to oral feeding ability in preterm infants. The most influencing factors were self-regulation with a prevalence ratio (PR) of 1.96 (1.16-3.34; CI 95%) and p = 0.012, followed by postural tone, high morbidity, and behavioral state (PR 1.91; 1.59; 1.56; CI 95%, respectively). In conclusion, despite meeting the oral feeding readiness criteria, most preterm infants were still not able to feed orally. There are other factors affecting oral feeding ability in Indonesian preterm infants.

Correlation of facial anthropometry data of late preterm newborns and oral feeding readiness

OBJECTIVE

To correlate nine facial anthropometric measurements with the readiness for oral feeding of late preterm newborns using an orogastric tube.

METHODS

Observational study, carried out in two institutions in Maceió, Alagoas. Fifty-two newborns participated. A single measuring of nine facial measurements and daily measuring of the interface area for fixing the tube was performed. For readiness assessment, the Premature Oral Feeding Readiness Assessment Scale was used.

RESULTS

An average readiness of 28.81 (± 3.18) was observed in the first evaluation and 30.65 (± 3.23) in the second. Most facial measurements are correlated with weight. There was a positive and slight correlation between glabella-subnasale distance and readiness. No correlation was observed between the area of the tube fixation interface and facial measurements.

CONCLUSION

It is concluded that the glabella-subnasale measurement is positively correlated with the readiness for oral feeding in late preterm newborns who used an orogastric tube for feeding.
